Question

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written

using function notation?
flv -v+
f(x) = - 3x + 4
f(x) = - *x+
f(V) = - 3y + 4

Answer 1

b) y = f(x) = -3x+4

Explanation:

Explanation

Given that the equation 9x+3y =12

Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form

y = f(x)

3 y = 12 - 9x

`y = (-9x+12)/(3)`

y = -3x+4

The function represented by y = -3x+4
